normally never have to be changed!

Adjusting the Edge Stop

For post-bed-machines a pneumatic stop is attached at the machine bed. This
stop is activated by a pneumatic toggle switch.
The stop width is adjusted either by shifting the cylinder "1" or by shifting the
stopper "2" inside the cylinder.

Knife speed

The maximum knife speed is adjusted by MJF. By the rotary knob (h) (fig.2)
the knife speed can be regulated.
With the left potentiometer on the control board (fig.5) the maximum
blade speed can be adjusted and with the right potentiometer the
minimum blade speed.
These settings are made prior to delivery and should not be changed!
8.0 Knife switch-on delay time
By knife switch-on delay time one understands the time from the knife
lowering impulse to the knife approach impulse.
3 time adjustments are possible:
1. Rotary switch 1 to 0 = 0.1 sec (preset)
2. Rotary switch 1 to 2 = 0.5 sec
3. Rotary switch 1 to 4 = 1.0 sec
Likewise one can affect the switch-on time over the throttle in the inlet to the
remote cylinder.
At the following procedures a cutting test must be made
(see item 3.0):
- changing the upper knife
- changing the lower knife
- changing the stitch plate
